Apparently Doom is not the only game being ported or modded by fans over and over to run on the most unusual things. Finnish modder Pekka Väänänen was able to make Quake work on a Hitachi V-422 oscilloscope, an item that's normally used to observe electrical signals.

Obviously, Quake looks quite different on an oscilloscope's screen, more like a game for the Virtual Boy and not for PC.
